大海的蓝天空比不上天空的晴大海给不了
[dà hăi de lán tiān kōng bĭ bù shàng tiān kōng de qíng dà hăi jĭ bù le]
The Blue Sky Over the Ocean Can't Match the Clear Sky, What the Ocean Can't Give. It's a rather poetic way to express that sometimes we strive for things that we think will bring happiness or satisfaction, but find they pale in comparison with what we already have or what remains just outside our grasp, like the sky versus the ocean.
